I never really became part of the community until much later, actually, with no disrespect to the Unreal community, but I felt it a little cliquey, I found the HL community much more friendly. So where are we now. Well, obviously I run PP in my spare time and I play as many maps...
and even for Half-Life 2, the use of a so called JoyStick Mapper application that map a joystick action to mouse or keyboard inputs. These tools really improve the experience of your XBox 360 Controller on Mac.
